What Happened
Elizabeth A. Gasser, EVP and Chief Strategy Officer of Tandem Diabetes Care (TNDM), had restricted stock units (RSUs) convert into 2,600 shares on Feb 17, 2026.

Key Details

  • Transaction date: 2026-02-17; Form 4 filed 2026-02-19 (filed within the normal 2-business-day window).
  • Conversion (code M): 1,503 and 1,097 RSUs converted into shares (gross = 2,600).
  • Tax withholding (code F): 887 and 647 shares withheld at $18.95/share = $16,809 and $12,261 (total $29,070).
  • Net shares delivered to insider: 2,600 − 1,534 = 1,066 shares.
  • Footnotes: Withholding was done by Tandem to satisfy tax obligations (no open-market sale). RSUs were awarded under the 2023 Long-Term Incentive Plan (awards from 2023 and 2024) and each RSU converts to one share (or cash at the company’s discretion). Some securities are held by The Gasser Family Trust, of which she is a co‑trustee. Vesting schedules per the awards: 33% on a specified date, remainder in quarterly installments (see filing footnotes).
  • Shares owned after the transaction: Not specified in the provided excerpt of the filing.

Context
This was a routine RSU vesting event rather than an open-market purchase or sale. The M code reflects conversion of RSUs into shares; the F code reflects shares withheld by the company to cover tax withholding (common practice). Because no open-market sale occurred, this transaction does not indicate a directional buy/sell decision by the insider.
